Abstract

The oriented attachment of hydroxyapatite (HAP) nanorods was achieved through a hydrothermal treatment. The nanorods were arranged in order along the c-axis of the HAP. These formed ca. 3.5 slip-shaped pores between the rods. High-resolution transmission electron (HRTEM) also revealed that single crystals of HAP may grow in the [0 0 2] direction of the HAP structure. This work extends the understanding of the potential for using biomimetic principles to synthesize bone-like composite materials.

摘要

通过水热法实现了羟基磷灰石（HAP）纳米棒的定向附着。纳米棒沿HAP的c轴有序排列。这些纳米棒之间形成了约3.5个条状孔隙。高分辨率透射电子显微镜（HRTEM）还显示，HAP单晶可能沿HAP结构的[0 0 2]方向生长。这项工作拓展了对利用仿生原理合成类骨复合材料潜力的认识。
